EDGE snT'rnR AND BURNISHER.

To all whom t may concern.'

citizen of the Chicago, in the of Illinois, useful Improvements Edge Setters and Burnishers, of which the following is a specification.

he invention relates to a combined edge setter and sole burnishing device for use in the manufacture of shoes.

One of the objects of the invention is Sto provide a burnishing device for burnishing or polishing the edge parts and the soles of shoes.

Another object is to provide a means for heating the device and fo r maintaining the ,temperature thereof substantially constant.

Another object is the provision of adjusting means and an indicator therefor, for adjusting the edge setter for soles of different thicknesses.

Further and more specific objects of the invention will become persons skilled in the art tion of the following readily apparent to from a consideradescription taken in conjunction with the drawings, wherein:

Fig. 1 is a side elevat ion of the device 3 3 of Fig. 1.

In all the views the same reference characters are employed to indicate similar parts.

The cylinder 5 is the roll, or polishing surface, to be heated and used for polishing soles, and edges of the soles, of shoes.

In this particular instance the roll, or cylinder is to be heated by electricity.

A cylinder heating means is placed on the inside of the cylinder 5 and supported by an insulating disk, The heating element may,

7 `and 8, at each end.

therefore, be bodily slipped into the cylinder, or roll 5, or

taken therefrom without the connections.

disturbing any of Av wire of suiicient size for heating the cylinder and its parts is wound about the cylinder 6 into a coil 9 for connection between terminating located' on the insulating lbinding posts 10 and 11, disks 7 and 8, re-

s ectivel The electricity ma be brou ht P Y Y g to the device by the wires 12 and are connected to the r posts.

13 which espective binding -seriai No. 403,260.

Inside'of the" cylinder or ytub`en6 is a thermo responsive device, 14, consisting of an insulating base, 15, and an expansion bar'l6. The 'bar is secured to the base under the binding post 17, atone end, and is free to make contact with the terminal-18 at i the other end. When the bar is heated' to a temperature above the temperature to be maintained on the outside of the cylinder 5, it expands into the position shown in dotted lines, and .thereby opens the heating circuit,

when the cylinder cools the bar closes thev circuit. y

The binding post 11 is directly connected by the wire 2O to the binding post 17, while thev contact 18 is connected by the binding post 21 and wire 22 to the end 23 of the heating coil 9.V Thel other terminal of the heating coil'is connected direct to the binding post 10. By this arrangement the thermo-responsive device and the heating coil are placed in series circuit with each other, so that when the circuit is opened by the thermo-responsive device the current will no longer flow through the heating coil. The current controlling device in the tube 6 is substantially sealed therein and no drafts tained substantially constant, and not modiy fied by outside inuences.

One end of the cylinder 5 is out turned to provide a bead 24 which is a part of the edge of the end surface of the cylinder. Located upon the cylinder 5 is a slid-able ring 25 having a suitable surface 26, co-operating with the bead 24. The arrangement is such that the surface 26 maybe adjusted axially with reference to the bead 24 by a handle 27, to provide. the proper space between the parts 24 and 26 to compensate for soles of Idifferent thicknesses.

Around the sleeve 25 is a support, 28, slid'able with the sleeve and operable by a handle 27.

A short shaft 30 carries on its inner end a mite-r gear 31. The handle 27 is secured to the shaft 30, as by a pin 32, or otherwise. The gear 31 is in mesh with a miter pinion 3 which is fixed on the c nd of the rotatable shaft 34. The shaft 34 is threaded as at 35, and the bearing 36 is threaded for the shaft. Collars 87 Vand 38 prevent axial movement of the shaft 34, so that when the shaft 34 is rotated the standard 36 of the the insulating disk 7 as by rivets 48 or the support 28 associated with the sleeve 25 is moved axially of the cylinder 5, so that the space between the annular bead 24 and the end 26 of the sleeve 25 may thus be varied for the purpose desired.

Rotating with the stub shaft 30 is an index, or pointer, 40, which is moved over a scale 4l, on the disk 42, when the handle 27 is rotated. This will indicate relatively at all times the distance between the parts 24 and 25. The support 28 is provided with two legs, 43 and 44, whichride along the shafts 34 and 45, when the handle 27 is rotated. A stationary support 46, provided with an upstanding leg 47 is connected to like. This end of the cylinder 5 is also provided with an outstanding annular bead 49, which may be either larger or smaller than the bead 24, and in some instances may be advantageously used Without the bead 24 or the ring 25.

When the surface of the cylinder ,is heated by the heating medium,the shoe soles are polished by rubbing them energetically over the surfaces of the cylinder 5 or the beads 34 and 49, and in contact with the surface 26 of the ring 25, which operation will be readily understood by persons skilled in the art.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. A device for burnishing the surfaces of shoe soles, having in combination a xed perature of the outer cylinder substantially constant. l

2. A device for burnishing. the surfaces of shoe soles having in combination a fixed non-rotatable outer cylinder providedl with an outwardly extending bead; a ring slidable on the cylinder providing a surface to form with the bead an adjustable `edge setter; means to axially adjust the ring with respect to the bead; a closed cylinder within the outer cylinder; a dial `and index to indicate the extent of the adjustment; and' a heating device between the cylinders and a temperature controlling device within the inner cylinder and removable therewith `as a single unit.

In testimony whereof I hereunto subscribed my name.
